To all 40720222 it may concern.

Be it known that I, RUPERT BnnYLnY, a citizen of the United States,residing at Paincsville, in the county of Lake and State of Chio, haveinvented a certain new and useful Improvem nt in Car Stops, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanyingdrawings.

This invention relates to that class of devices known as friction carsteps which comprise shoes carried by the opposed rails of a track andslidable from a normal positiou thereon to a second position, the shoescarrying the advancing wheels of the rolling stock and sliding under theweight of their burden along the rails until the fricticn between theshoes and rails overcomes the momentum of the rolling stock, or untilthe shoes come in contact with abutments, or until the rolling stockengages a bumper. Upon subsequent movement of the rolling stock in theopposite direction, the shoes are returned by the wheels to normalposition wherein they are stopped by suitable obstructions, usually fishplates which connect adjoining rails.

lVith a view of eliminating the faults possessed by prevailing car stopsof the above mentioned class, my invention com prehends the followingprincipal objects:

To provide a friction car stop that is equally suitable for useindependently of, or in conjunction with, a stationary bumper of a typewherein the bolster is sustained by structural members that are fasteneddirectly to the track rails, the car stop being so designed as to escapeobstructions situated along the rails and common to the aforesaid typeof bumper;

To provide a friction car stop which, when used alone or with astationary bumper, 0 uses no loss of track space;

To provide a friction car stop wherein the shoes are returned to normalposition by the revolving wheels of the rolling stock and withoutappreciable friction;

To provide a shoe for friction car stops which is of unique design,being preferably formed as an integral casting, and wherein thepull-back is spaced from the wheel obstructing portion so that as theadvancing wheels enter the stop they ride over the pull-hacks of theopposed shoes and drop directly onto the rails, thereby preventingdistortion of the shoes through continued use and insuring throughoutthe life of the stop a flat bearingsurface of the shoes upon the railsat all points throughout their lengths;' A

To provide a shoe for friction car stops which as above mentioned ispreferably formed .as' an integral casting and having that portion whichfrictionally engages the rails of a softer quality of metal than thatportion of its pull-back which is engaged by the wheel during the returnof the stop to normal position thereby to acquire the maximum efficiencyduring the stopping of the rolling stock and to render as easy aspossible the return of the stop to normal position; and

To provide a friction'car stop which, by suitable rigging, may beshifted with respect to the rolling stock sufficiently to di engage thepull-backs of the opposed shoes from the wheels wherewith they normallyengage during the return movement ofthe stop so that the manualOPGTZItlOIlOf shifting the car along the track, commonly known aspinching a car, may be as easily performed as under ordinarycircumstances.

Further and more general ob ects are to provide a highly efficient carstop that is particularly convenient of installation, is very durable,andis comprised of few parts that are cheap of manufacture and easy ofassembly. v

The foregoing objects, with others hereinafter appearing, are attainedin the construction illustrated in the accompanying drawings whereinFig. 1 is a side elevation of my improved car stop mounted upon a-.traclr; Fig. 2 1s a fragmentary plan view of the stop; Figs. 3, i and 5are sectional details on the lines 38, 44 and 55, re spectively, of Fig.1; 6 shows a section of track in side elevation, at the right hand endof which .is situated a stationary car bumper and atthe left hand end ofwhich is shown in normal position my improved friction car stop; Fig. 7is a view, similar to Fig. 6, showing a car engaging the stationarybumperwith the wheels of the advancing truck resting upon the frictioncar stop; Fig. 8 shows the car proceeding away from the stationarybumper and. returning 7 the friction stop to normal position; Fig. 9 isa sectional view taken longitudinally of the track and showing thefriction car stop fso adjusted with respect to the car that the car: maylee-shifted along the track in the direction indicated by the arrow withthe customary ease; Fig. 10 is a fragmentary plan view of what isshowrnin'Figcfigtasnd Fig. 11 isva sectional detail of one of theabutineiits wherew th, under certain oond-if t-ions, the friction carstop engages, the sectionbeing taken on the,line'11' '11 ofF'ig: 6. Thefriction car stop is comprised of right and left hand slices, eachbeingprei'erably formed of an integral casting? Each shoe includes acomparatively longirail engaging I section 1, the" uppersur faceofwhiclnad jacent its it'orwardend, merges into an up-' 'wardl'y inclinedcurved wheelobstr'ucting portion 2.

Spaced longithe section 1 is apart which Ishall term 7 p This has a bearing upon the ball of the rail ofconsiderable extent and it gradually tapers froma relatively thin edgeat the rear end of the shoe to a suitable elevation where it joins,through a horizontal surface 6,"aj'downwai'dly' curvedportion7 thatdescends to the top surface of the rail. Consequently between the parts,

designated-A and? thewheele igaging surface of the rail is exposed. Thepull-back t 5' is connected" to thesection 1 by neans of arlaterally disposed angular beam 8 shown in cross section in Fig; 4. On oppositesides of the pull-bacli5,-and at about the rear end of beam 8, are lugs10 whichextend' down along side and beneath the-ball of the railin'toclose proximity. to the web thereof, as

shown in detail in Fig. 3. At the forward extremity of the shoe, thesection 1 is formed with lugs-11- which embrace the ball of" the railbut do not e'xtendbelow the same. The

formation of these lugs is best illustrated in Smaller lugs 12 areformed on opposite sides of the section 1 a suitable distance rearwardlyof the [lugs/111 The lugs 12, likethose just described; are no deeperthan the ball of the T he upper ends of the portions 2' of the opposedshoes are tied together by a rod or bolt 13, and are maintained a hireddistance apart by a tubular spacer 14-that is applied to' the bolt orrod.

There is, however,apeculiar advantage in a stationary bumper;

so f the conjoint use-of a it'rictioncarstop and" i In Figs. 6; 7- and8' v I have shown ahighly. desirable type of Y bumper, designated B,andk comprising; a' 255 j bolster]; that is sustained at an elevation toreceive the bumper engaging partcofa car Cby strut-s1) and tensionmember6 which may be constituted of rails havinghorizontalportions 5that-lie'on thet-ies (not shown) along side the rails A an d arefastened to said. rails by bolts; bf and spaced 1 r therefrom bystringers-b through which, p

Iam permitted to" shorten the lugs 11 and12 in'the manner stated becausethey have, only the onei'f-nnctionof f iinaint aining the shoes againstlaterali displacement. Were it necessary, as in-p 'iorf '7typ'esoffriction car stop 'wher ewi'thl am familiar, to engage the lugsat the forward? ends of the shoes beneath the balls of the rails, itwould not. be possible to 'use the stop "in'con'jn'nctionwith bumpers ofthe type above' descr'ibed I ,l lllf x The difference between myimproved A bumper and the prior ones referred to and which difference isresponsible for this mod ification of the lugsand the benefits arisingtherefrom, is the space between the pull-back 5 and the section 1of'each shoe. W'ithout su'ch'a space, the continual hammeringof thewheels upon thecomparativelythi'npor ti'ons of the shoes,"assaidwheels'drop from V illiG'Pilll-bilCkS when entering the stop, would beliable to cause a displacement of themetal that would result in theshoesassumin a rocker shape, andif such a condition should i 1 develop andthe'lu gs were short they would soon rise so high wit h frespect' to thethat they wonld'be' of no eflt'eet;

In the bumper installation, asabove derails scribed and asillustrated'in Fig s;- 6',.7:.and: l

' 8, the abutments'15' are" employed merely as 'a safeguard? incase'thebumper fails. They 75- lugs 11 engage'the abutments' 1'5 being'1 remembered'tha't we arenow considering the are placed beyond thelimit of normal at Vance movement of the friction car stop a' will beseen by reference to Fig. 7.

If the rolling stock is to be stopped .by engagement with a fixedobstruction, rather than solely through the action of the friction carstop, it is better that the suspended load engage the obstruction,-thanthe trucks from which the load is suspended. This is for the obviousreason that by far the greater part of the momentum is in the suspendedload. In the bumper installation, the friction car stop serves to retardthe movement of the rolling stock, while the bumper serves to positivelyarrest the move ment of the load thus avoiding strains which wouldotherwise occur in the car structure between the body and the truck.

VJ hen the rolling stock is moved in the direction indicated by thearrow in Fig. 8, the wheels previously described as the rear wheels ofthe truck ride 05 the pull-backs 5 and the front wheels withdraw fromthe portions 1 and bear upon the rails through the spaces between saidportions and the pull-backs. aforesaid direction said wheels engage theupper ends of the inclined portions 7 (as indicated in Fig. 1 where thetread of the wheel is represented by the blOlZCGH line and shove thestop along the track until the lugs 10 engage the fish plates a Thesefish plates arrest movement of the car stop and the car wheels ride overthe pull-backs 5, leaving the stop in normal position for its nextoperation. It may be explained in this connection that the portion ofeach pull-back, engaged by the car wheel during the return movement ofthe stop, is hard ened, as represented by the shading in Fig. 1, for thedouble purpose of preventing undue wear of the shoe and for reducing thefriction between it and the wheel. The rail engaging portions of theshoe are left as.

soft as practical so as to increase the friction between the shoe andthe rail when the shoe is being slid forwardly under load.

It frequently becomes necessary to shift cars along a track by manualpower, an operation commonly referred to as pinching a car. This is doneby means of a crow-bar like implement, called a pinch bar, which isadapted to be wedged between the rail and a wheel of the car andalternately raised and lowered. A man is indicated in dotted lines inFig. 9 in the act of pinching the car in a direction indicated by thearrow appearing on the car in this View. In order to avoid interferencewith this operation by the friction car stop the same is shifted withrespect to the car by suitable rigging. In Figs. 9 and 10 this riggingis shown as comprised of a Y-shaped yoke 16 that is engaged with the carstop and has pivoted to the end of its stem a cam lever 17 which isswung to the position shown in the drawing, 1n whlch position it may beheld by a ring As the car continues in the adapted to be engaged throughthe terminal link of a chain 18 that is connectedby a hook 19 to thecar-axle 20. lVhen the lever 17 is engaged through said link and is 21,it advances the car stop with respect to the car enough to withdraw thepull-backs from the wheels. The car may now be moved forwardly withcomparative ease, thecar stop slidingfreely along the track during theoperation.

Having thus'de scribed my invention, what I claim is:
